Critical round test

The purpose of this experiment is to investigate the transverse vibrations of the beams and to obtain the critical speed of the rotating axes.
When an axis whose center of mass does not coincide with the centers of its bearings rotates, large deformations occur in the axis at certain rotational speeds. This phenomenon is called rotation and the speed at which this phenomenon occurs is called critical speed.
The test device consists of a rotating axis, two central bearings, two fixed bearings and a three-phase motor of 10,000 revolutions. A coupling is connected to the front part of the engine, which is connected to the shaft under test
